Cautions regarding the use of the function
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The RCTA function is only a supplementary function which alerts the driver that a vehi-
cle is approaching from the right or left at the rear of the vehicle. As the RCTA function
may not function correctly under certain cond itions, the driver’s own visual confirma-
tion of safety is necessary. Over reliance on this function may lead to an accident
resulting death or serious injury.
